Complete tumor remission and suppression of recurrence/metastasis demonstrated in animal models of triple-negative breast cancer and colorectal cancer

A new preclinical study from The University of Texas MD Anderson Cancer Center has identified a gut bacterium that, when combined with short-term fasting, helps prepare the small intestine to regenerate more effectively after radiation damage. 

CHANGWON, South Korea — Korea Institute of Materials Science (KIMS), led by President Chul-jin Choi, announced that a research team led by Minyoung Lee and Sunggyu Park of the Bio & Health Materials Research Division has developed a plasmonic-based liquid biopsy platform capable of ultrasensitive detection of KRAS mutations in the blood and urine of patients with early-stage colorectal cancer. By analyzing matched tumor tissue, plasma, and urine samples from patients with Stage 0 and Stage I colorectal cancer, the researchers demonstrated over 90% concordance in KRAS mutation status across the three specimen types, supporting the platform's potential as a non-invasive precision cancer diagnostic technology.
